27.5.1 Sleepy Mode Current Consumption
The Rabbit 3000 supports designs with very low power consumption by using features
such as the sleepy modes and self-timed chip selects. At the low frequencies possible in
the ultra-sleepy modes (as low as 2 kHz), the external memory devices become significant
factors in the current consumption unless one of the short or self-timed chip selects are
used.
Figure 27-7 shows a typical current draw for the sleepy modes.
